Nobody wants to ship software with lots of bugs, performance issues, and low customer satisfaction. Continuous integration and code reviews help prevent this... but who has the time, right? Well, agile teams make time.
Agile developers focus on sustainable development–not heroics. Sustainability is about good estimation, effective branching strategies for managing code, automated testing to protect quality, and continuous deployment to get fast feedback from users.
Adopting sustainable development practices requires a discipline most of us aspire to–but often struggle to realize–as individuals. That's because nobody can go agile in a vacuum. The culture of the entire organization has to rally behind it. That means getting project leaders to buy into the notion that quality is more important than scope or schedule, which is often the hardest part of adopting agile.
